Mushure memakore ekuvandudzwa, tekinoroji yekugadzira tambo dzeoptical yakura zvikuru. Pamusoro pehunhu hunozivikanwa hwekukwanisa kukuru kweruzivo uye kushanda zvakanaka kwekutumira, tambo dzeoptical dzinodiwawo kuti dzive nezvakanaka zvehukuru hudiki uye huremu hwakareruka. Hunhu uhu hwetambo dzeoptical hwakabatana zvakanyanya nekushanda kwefiber yeoptical, dhizaini yechimiro chetambo dzeoptical uye maitiro ekugadzira, uye zvakare hwakabatana zvakanyanya nezvinhu zvakasiyana-siyana uye hunhu hunoumba tambo dzeoptical.
Pamusoro pemafiber e optical, zvinhu zvikuru zvakagadzirwa mu optical cables zvinosanganisira mapoka matatu:
1. Zvinhu zvePolymer: zvinhu zvechubhu yakasimba, zvinhu zvechubhu yakasununguka yePBT, zvinhu zvePE sheath, zvinhu zvePVC sheath, mafuta ekuzadza, tepi inovhara mvura, tepi yepolyester
2. Zvinhu zvakasanganiswa: tepi yakasanganiswa yealuminium-plastic, tepi yakasanganiswa yesimbi-plastic
3. Zvinhu zvesimbi: waya yesimbi
Nhasi tinotaura nezvehunhu hwezvinhu zvikuru zviri muwaya ye optical uye matambudziko anowanzoitika, tichitarisira kubatsira vagadziri vewaya ye optical.
1. Zvinhu zvechubhu zvakasimba
Zvizhinji zvezvinhu zvekutanga zve tight tube zvaive zvekushandisa nylon. Zvakanakira ndezvekuti ine simba rakati uye inodzivirira kupfeka. Dambudziko nderekuti mashandiro ekuita basa haana kunaka, tembiricha yekugadzirisa yakamanikana, zvakaoma kudzora, uye mutengo wakakwira. Parizvino, kune zvimwe zvinhu zvitsva zvemhando yepamusoro uye zvakachipa, zvakaita sePVC yakagadziriswa, elastomers, nezvimwewo. Kubva pakuona kwekugadzirwa, zvinhu zvinodzora moto uye zvisina halogen ndizvo zvinonyanya kudzorwa nezvinhu zve tight tube. Vagadziri vetambo dze optical vanofanira kutarisisa izvi.
2. PBT zvinhu zvechubhu yakasununguka
PBT inoshandiswa zvakanyanya muzvinhu zveoptical fiber zvakasununguka nekuda kwehunhu hwayo hwakanaka hwemakanika uye kuramba kwayo makemikari. Hunhu hwayo hwakawanda hwakabatana nehuremu hwemamorekuru. Kana huremu hwemamorekuru hwakakura zvakakwana, simba rekudhonza, simba rekuchinjika, uye simba rekukanganisa zvakanyanya. Mukugadzirwa chaiko uye kushandiswa, kutarisirwa kunofanirwa kupihwa pakudzora kushushikana kwekubhadhara panguva yekubatanidza matambo.
3. Mafuta ekuzadza
Fiber ye optical inonyatsonzwa OH–. Mvura nehunyoro zvinowedzera zvidimbu zvidiki pamusoro pe fiber ye optical, zvichikonzera kudzikira kukuru kwesimba re fiber ye optical. Hydrogen inogadzirwa nemakemikari ari pakati pehunyoro nezvinhu zvesimbi inokonzera kurasikirwa kwe hydrogen ye fiber ye optical uye kukanganisa kunaka kwetambo ye optical fiber. Saka, kushanduka kwe hydrogen chiratidzo chakakosha chemafuta.
4. Tepi inovhara mvura
Tepi inovhara mvura inoshandisa chinonamira kunamira resin inonwisa mvura pakati pemachira maviri asina kurukwa. Kana mvura ikapinda mukati metambo ye optical, resin inonwisa mvura inokurumidza kunwisa mvura uye kuwedzera, ichizadza mipata yetambo ye optical, nokudaro ichidzivirira mvura kuti isayerera kwenguva refu uye ne radially mutambo. Pamusoro pekusagona mvura zvakanaka uye kugadzikana kwemakemikari, kukwirira kwekuzvimba uye mwero wekunwisa mvura panguva imwe chete ndizvo zvinonyanya kukosha zvinoratidza tepi inonwisa mvura.
5. Tepi yesimbi yepurasitiki yakasanganiswa uye tepi yepurasitiki yakasanganiswa yearuminiyamu
Tepi yesimbi yepurasitiki yakagadzirwa nesimbi uye tepi yealuminium yakagadzirwa nepurasitiki iri mutambo ye optical inowanzo putirwa kwenguva refu yakashongedzwa ne corrugated , uye inoumba sheath yakazara ne PE outer sheath. Simba re steel tape/aluminium foil ne plastic film, simba rekupisa pakati pematepi e composite, uye simba re bonding pakati pe composite tape ne PE outer sheath zvine simba guru pakushanda kwetambo ye optical. Kuenderana kwemafuta kwakakoshawo, uye chitarisiko che steel composite tape chinofanira kunge chakati sandara, chakachena, chisina ma burrs, uye chisina kukuvara kwemuchina. Pamusoro pezvo, sezvo steel plastic composite tape ichifanira kuputirwa kwenguva refu kuburikidza ne size die panguva yekugadzira, kufanana kweukobvu uye simba remuchina zvakakosha kune mugadziri wetambo ye optical.
